How can I make a label display how many times a button is hit?

I have a button and a label. I want to press the button and display on the label the total of the times pressed multiplied by $5.
For example, I press the button 3 times and it displays in the label $15.
Below is what I have so far....

private void button1_Click(object sender, EventArgs e)
{
label1.Text = "0";
int count = System.Convert.ToInt32(label1.Text);
count++;
label1.Text = count.ToString();
}


It displays "1" and allows me to hit the button only once....

you initialize int count evrytime the button is pressed

place int count = 0; outside the button1_Click function

Code:

---

                int count = 0;

private void reset()
        {
        label1.Text = "0";
        count = 0;         
}

 private void button1_Click(object sender, EventArgs e)
        {
        count++;         
        label1.Text = count.ToString();
        }

Great! Thanks. It worked. Now, it leads me to another question...how can I format this to output in currency. For example, if the button is pressed once, then 4 would appear....but how can I make it $4.00?
Thanks

Code:

---

public partial class Form1 : Form
    {
        public int count = 0;
       
        public Form1()
        {
            InitializeComponent();
        }


        private void reset()
        {
            label1.Text = "0";
            count = 0;
        }
        private void button1_Click(object sender, EventArgs e)
        {
          double total = 0;
                count++;
                total = count * 4.00;
                label1.Text = total.ToString();       
        }
    }

Ok, I kind of figured it out, but isn't there a more efficient way of doing it than below....

Code:

---

label1.Text = total.ToString("$" + total);

---

Code:

---

String.Format("Money: {0:C}", total)
